LANSING, MI -- Two custodial workers are facing a felon charge each after police say they caught them cooking meth at the Insurance Institute of Michigan late Wednesday.

Lansing District Judge Patrick Cherry arraigned Eric Welch, 32, and Amanda Wagner, 31, both of Lansing, each on a charge of felony operating/maintaining a meth lab. For Welch, the charge is his fourth offense notice, which could amplify a potential sentence.

Lansing responded to 332 Townsend St. in downtown Lansing about 11 p.m. Wednesday on a report of a possible larceny. The address is a building owned by the Michigan Wine and Wholesalers Association.

When police arrived, they say they found Welch and Wagner cooking meth in space rented by the Insurance Institute of Michigan.

Cherry set Welch's bond at $35,000 cash surety and Wagner's at 10 percent of $7,500. He scheduled them to appear in tandem for a pretrial conference on Oct. 2 and preliminary examination on Oct. 4, both before Lansing District Judge Louise Alderson.

Operating/maintaining a meth lab is punishable by up to 10 years imprisonment and a $100,000 fine.
